During crude oil extraction, refining, production, and transportation, large quantities of toxic and flammable gases exist in the working environment. In the event of a gas leak, poisoning or explosions can easily occur, endangering lives and damaging equipment. The fixed gas leak alarms manufactured by factory CMC can continuously monitor gas concentration 24 hours a […]
What is a fixed combustible(flammable) gas detector?A fixed combustible gas detector, also known as a gas leak detection alarm, is installed in a fixed location to continuously monitor the concentration of combustible gases 24 hours a day. Including methane (CH₄), natural gas (mainly CH₄), LPG (mainly C₃H₈), propane (C₃H₈), butane (C₄H₁₀), and hydrogen (H₂). When
Many our customers often ask the same question:If there are several different combustible(flammable) gases leaking in one area, and their mixing ratios are not fixed, How many types of gas detectors need to be installed?The answer is one. Combustible gas detection is based on the Lower Explosive Limit (LEL) of gases. If multiple flammable gases
CMC Fixed Toxic and Combustible Gas Detector (Standalone 24V Power Supply Model) Introduction: This fixed toxic and combustible gas detector offers two signal output options: a three-wire 4-20mA current signal or a four-wire RS485 bus. Its advantages include long transmission distance and strong anti-interference performance. It is suitable for industries such as petroleum, petrochemicals (refineries,
The Importance of Installing Gas Detectors at Gas Stations:The fuels stored and transported at gas stations, such as gasoline and diesel, are flammable, explosive, and volatile. A flammable gas leak could cause a serious safety incident. Therefore, installing flammable gas detectors has become a crucial safety management measure for gas stations. The wireless combustible gas
Ammonia(NH₃), also known as liquid ammonia, is a colorless gas with a pungent odor. It is both flammable and toxic. Ammonia can be used for refrigeration and is widely used in various types of cold storage rooms, laboratories where ammonia is present, and ammonia storage warehouses. The following four main types of cold storage are
During tunnel construction, toxic and hazardous gases are extremely dangerous and can easily lead to serious safety accidents. Therefore, regulations require that industrial gas detection systems be used to monitor these gas concentrations and ensure proper ventilation. If gas concentrations exceed the specified limit, construction is prohibited. Common flammable and toxic gases in tunnel construction:
The CMC-600KZ series gas alarm controllers, manufactured by CMC company, typically require Four-wire 4 × 1.5 mm² RVV cable for RS-485 bus signal transmission. The CMC600 series gas detectors are connected to the controller with four-core cables equipped with a metallic shielding layer, which effectively resists interference: In addition, 4 × 0.75 mm² or 4
Liquid ammonia gas alarm mainly detects the concentration of liquid ammonia gas. When the ammonia concentration exceeds the normal level, it will sound an alarm in time. The industrial gas alarm system is mainly composed of gas detectors and controllers. Toxic gas detectors are widely used in cold storage, food factories, sewage treatment, metallurgy, petroleum,
A combustible gas alarm is an early warning device that mainly detects the gas content in the air or working environment. It plays a vital role in ensuring the safe use of gas in all areas of society. CMC produces fixed commercial and industrial combustible gas detectors, which are often used in large-scale industrial
